Costa Rica Option to Purchase Agreement: Nosara Guide

The Costa Rica option to purchase agreement is the first document with real legal teeth in a Nosara property deal. It takes the house or lot off the market, fixes the price, sets your deposit, and decides whether you walk away with your money if due diligence turns up a problem. Most buyers spend weeks negotiating price and about twenty minutes reading this contract. That ratio should be reversed, because almost every expensive dispute we see in Nosara traces back to a vague clause in the option.

📊 By the numbers: A typical Nosara option calls for a 10% deposit held in third-party escrow, a 21 to 30 day due diligence window, and closing within 30 to 90 days. Under Article 1055 of Costa Rica's Civil Code, a promise of sale whose performance is not demanded within one month of becoming enforceable expires on its own.

This guide walks through what the option actually is under Costa Rican law, each clause that matters, the contingencies Nosara buyers specifically need, and the mistakes that cost people their deposits. If you are earlier in the process, start with our Nosara buyer's guide and come back once you have a property in mind.

What a Costa Rica Option to Purchase Agreement Actually Is

In Costa Rica, a real estate sale usually happens in two legal steps. First, buyer and seller sign a private contract that commits them to the deal on stated terms. Second, a notary public (who in Costa Rica is always a licensed attorney with an additional notarial qualification) executes the transfer deed (escritura de traspaso) and presents it to the Registro Nacional, where ownership officially changes.

The first contract comes in a few flavors, and people use the names loosely:

Opción de compra venta (option to purchase): The seller commits to sell at a fixed price, and the buyer gets a defined period to decide whether to go through with it. The buyer's main exposure is the deposit.
Promesa recíproca de compra venta (reciprocal promise of sale): Both parties promise to complete the sale. This is closer to a standard North American purchase contract, and either side can generally demand performance.
Contrato de compra venta privado (private purchase agreement): A catch-all term agents use for the same kind of document.

In the Nosara market, nearly every deal starts with a document titled "Option to Purchase Agreement," usually bilingual, usually drafted from a template supplied by the listing brokerage or the escrow company. The label matters less than the text. A document called an option can contain reciprocal obligations, and a document called a purchase agreement can let the buyer walk away freely during due diligence. Your attorney should read it for what it actually says.

Why the Option Matters More Than the Deed

The transfer deed is largely standardized. Notaries follow required formats, and the Registro Nacional will reject a deed that does not meet its requirements. The option, on the other hand, is a private contract, and almost everything in it is negotiable. That is where the risk allocation happens: who holds the money, what happens if the water letter never arrives, who pays for a survey correction, and what happens if the seller simply changes their mind.

Costa Rica's Civil Code also has a detail that surprises foreign buyers. Article 1054 says ownership transfers on the day of the sale, not on the day of the promise. Signing the option gives you contractual rights against the seller, but it does not make you an owner. Article 1055 adds that a promise of sale whose performance is not demanded within one month of becoming enforceable lapses. In practice, that means dates in your option are not decoration. If the closing date passes and nobody acts, your ability to force the sale can evaporate quickly.

💡 Key insight: The option decides who carries each risk in the deal, and the deed mostly records the outcome. Negotiate the option as hard as you negotiated the price.

The Clauses That Matter in a Nosara Option Agreement

Below is a clause-by-clause breakdown of a well-drafted option for a Nosara property. Use it as a checklist when your attorney sends you a draft.

1. Identification of the Parties

The contract should name the actual registered owner exactly as it appears in the Registro Nacional. In Nosara, a large share of properties are held in a Costa Rican corporation (a Sociedad Anónima or SRL). If so, the seller is the company, not the person you have been talking to, and whoever signs must have registered legal authority to sell on its behalf. Your attorney should confirm this with a current corporate registry certification. We cover the corporate structure in depth in our guide to using a corporation to buy property in Nosara.

If you plan to buy through your own new corporation, the option should allow you to assign your rights to that entity before closing without needing the seller's consent again.

2. Property Description

A street address is not enough. The option should identify the property by:

Folio real number (the registry number, for example 5-XXXXXX-000 for Guanacaste)
Plano catastrado number (the registered survey)
Area in square meters as stated in the registry and survey
Any improvements, furniture, vehicles, or equipment included in the sale

That last bullet matters in Nosara, where many homes sell furnished and operate as vacation rentals. If the solar array, the generator, the surfboard rack, or the future rental bookings are part of the deal, list them in an inventory annex. Our article on what transfers with a turnkey vacation rental explains why this gets contentious. If you have not checked the registry details yet, read how to read a certificación literal and why the plano catastrado matters.

3. Price, Currency, and Payment Schedule

Nosara properties are almost always priced and paid in US dollars. The clause should state:

The total price in USD
The deposit amount and the date it must reach escrow
The balance due at closing
Whether any portion is paid outside escrow (the answer should be no)

Watch for sellers who ask for part of the price to be paid separately or "declared lower" on the deed to reduce transfer taxes. Under-declaring the value is illegal, it weakens your title insurance and future capital gains position, and it can leave you exposed if the deal collapses. Our closing costs breakdown shows what the transfer tax and registration fees actually add up to.

4. The Deposit and Escrow

The standard deposit in Nosara is 10% of the purchase price, sometimes 5% on larger deals or 20% on pre-construction. The contract should require the deposit to go to a licensed third-party escrow company, never to the seller, the seller's agent, or a lawyer's personal account.

Before any wire can land in escrow, the company will ask for your source of funds documentation under Costa Rica's anti-money laundering rules. Start assembling that paperwork before you sign, or you risk missing the deposit deadline. See our guides on source of funds documents and the escrow process.

5. Due Diligence Period

This is the clause that protects your money. It should specify:

Length: 21 to 30 calendar days is common. Ask for more if the property has water, access, or survey questions, or if you are buying land to build.
Start date: from the date the deposit reaches escrow, not the date of signing. Otherwise an international wire delay eats your review time.
Refundability: the deposit is fully refundable if you terminate for any reason, or for stated reasons, before the period ends.
Seller cooperation: the seller must provide documents and site access within a set number of days.
Notice method: how you terminate (email to named addresses is practical), and a clear statement that escrow releases the deposit to you on receipt of that notice.

The strongest version for a buyer says the deposit is refundable if the buyer, in its sole discretion, is not satisfied with due diligence. Sellers in a busy season may push back and want a list of specific reasons. That can be acceptable, as long as the list is broad and includes everything in the next section.

💡 Key insight: A due diligence clause is only as good as its start date and its refund trigger. A 30 day period that starts at signing and requires "material title defects" to cancel is much weaker than a 21 day period that starts at funding and allows cancellation at your discretion.

Nosara-Specific Contingencies to Write Into the Option

Generic templates are often written for San José condos or Tamarindo resales. Nosara has its own set of issues, and your option should name them specifically.

Water Availability

No water letter, no building permit. The option should make the deal contingent on a valid water availability letter from the local water provider (ASADA or AyA as applicable) or a registered well concession, in the buyer's name or transferable to it. This is the single most important Nosara contingency. Read the Nosara water letter guide before you sign anything.

Legal Access

Some lots in the hills above Guiones and Pelada reach the road through private easements that were never registered. Make the deal contingent on registered legal access from a public road. Our road access and easements guide covers what to verify.

Zoning and Building Rights

Parts of the Nosara area fall under a regulatory plan, and restrictions on density, setbacks, and height vary by zone. If you are buying to build, the option should be contingent on a zoning certificate (uso de suelo) that permits your intended use. Our building regulations guide goes deeper.

Maritime Zone and Environmental Status

Anything near the beach needs confirmation that it is titled land outside the maritime zone, or a clear understanding of any concession. Properties with streams or heavy forest need a check for riparian setbacks and forest restrictions. See titled vs concession property and cutting trees on your Nosara property.

Inspection and Survey

For homes, include a professional inspection contingency covering structure, roof, septic, electrical, and pest damage. For land, include a physical boundary survey that matches the plano. Our home inspection guide lists what inspectors in Guanacaste typically find.

Rental Performance (If You Are Buying an Income Property)

If the price reflects rental income, make the deal contingent on the seller providing booking platform statements, tax filings, and a list of future reservations, and state who keeps deposits for stays after closing.

Contingency	Why It Matters in Nosara	Who Usually Provides Proof
Clean title and no liens	Liens, annotations, and old mortgages can survive a sloppy closing	Buyer's attorney via Registro Nacional
Water availability letter	Without it you cannot get a building permit	Seller, from ASADA or AyA
Registered legal access	Many hillside lots use unregistered private roads	Buyer's attorney and surveyor
Zoning (uso de suelo)	Density and use rules vary by zone	Municipality of Nicoya
Maritime zone status	Beachfront may be concession land, not titled	Buyer's attorney
Physical inspection	Humidity, termites, and septic failures are common	Independent inspector
Survey match	Fences often differ from the registered plano	Licensed topographer
Rental records	Income claims drive price on turnkey rentals	Seller
Financing (if any)	Foreign financing is slower and less certain	Lender

💡 Key insight: List each Nosara risk by name in the contingency clause. "Satisfactory due diligence" is easy to argue about. "Receipt of a valid water availability letter" is not.

Closing Terms, Default, and Remedies

Closing Date and Extensions

The option should set a firm closing date and a simple mechanism for extensions, such as one 15 day extension at the buyer's request if a government document is delayed. Remember Article 1055. If the closing date arrives and neither party has acted, the promise can lapse after a month. Your attorney should calendar the deadlines and send formal notice if the seller stalls.

Choice of Notary

In Costa Rica, the buyer typically chooses the closing notary because the buyer pays the notary fees and the transfer costs. Make that explicit in the option. Using the seller's lawyer as your notary saves a little money and costs you an independent set of eyes. Our guide to hiring a real estate lawyer in Nosara explains the difference between a notary's duty and an advocate's duty.

Allocation of Closing Costs

The standard allocation in Costa Rica puts transfer tax, registration, and notary fees on the buyer, though this is negotiable. The seller normally pays their agent's commission and brings property taxes, luxury home tax, HOA dues, and utilities current through the closing date. Put the prorations in writing.

Buyer Default

If you back out after due diligence for no contractual reason, the deposit usually goes to the seller as liquidated damages, and the option should say that is the seller's sole remedy. Without that sentence, a seller could try to claim more.

Seller Default

This is where many templates are weak. If the seller refuses to close, the buyer should be entitled to:

Return of the full deposit, plus
An equal amount as a penalty (a mirror of what the buyer would lose), or
Specific performance, meaning a court order forcing the sale

Also consider asking your notary whether it is practical to formalize the option in a public deed and present it to the Registro Nacional. A recorded option puts third parties on notice and makes a double sale much harder. It adds cost and time, so it tends to make sense on higher-value properties or longer closing periods.

Dispute Resolution

Costa Rican court cases can take years. Many well-drafted options send disputes to arbitration at an established center in San José, with the language (English or Spanish) specified. The option should also say which language version controls if the bilingual text conflicts. Normally that is Spanish, so have your attorney confirm the Spanish text says what the English text says.

Option Agreement Terms: Weak vs Strong

Clause	Weak (Seller Friendly)	Strong (Buyer Protective)
Deposit holder	Seller's lawyer or agent	Licensed third-party escrow
Due diligence start	Date of signing	Date deposit reaches escrow
Refund trigger	"Material title defects" only	Buyer's sole discretion
Named contingencies	None	Water, access, zoning, maritime zone, inspection, survey
Closing notary	Seller's attorney	Buyer's choice
Seller default	Return of deposit only	Deposit returned plus penalty or specific performance
Assignment	Not allowed	Allowed to buyer's corporation
Governing language	Unclear	Stated, with verified translation
Disputes	Local courts	Named arbitration center

Common Mistakes That Cost Nosara Buyers Their Deposits

These come up again and again, including with experienced buyers from the US and Canada.

Signing the agent's template without an attorney review. Templates are a starting point. They are rarely drafted with your specific property in mind.
Wiring the deposit before the source of funds file is ready. The escrow company holds or returns the wire, the deadline passes, and the seller accepts a backup offer.
Letting the due diligence clock start at signing. International wires and weekends can burn a third of your window.
Accepting "we'll get the water letter after closing." That promise has no value once the seller has your money.
Paying a portion outside escrow. If the deal fails, recovering money from an individual in another country is slow and expensive.
Ignoring the corporate seller. If the person signing lacks registered authority, the contract can be challenged.
Missing dates. Costa Rican law punishes inaction. Put every deadline on a calendar and have your attorney send formal notices.
Skipping scam checks. Fake sellers and forged powers of attorney do appear. Read our list of real estate scams in Nosara.

💡 Key insight: Nearly every lost deposit we hear about in Nosara came from a timing problem or a missing contingency. Both can be fixed on paper before you sign.

A Practical Timeline From Offer to Signed Option

Here is what a clean process looks like for a buyer purchasing a home in Playa Guiones or Playa Pelada, or a lot in Garza:

Step	Typical Timing	What You Do
Written offer accepted	Day 0	Send your attorney the listing and registry numbers
Attorney pulls title and corporate records	Days 1 to 3	Review early red flags before drafting
Option drafted or revised	Days 2 to 7	Negotiate contingencies, default terms, and dates
Source of funds file submitted	Before signing	Bank statements, sale documents, ID
Option signed	Around day 7	Electronic signature is common for remote buyers
Deposit wired to escrow	Within 3 to 5 business days	Confirm receipt in writing
Due diligence period	21 to 30 days from funding	Inspection, survey, water, access, zoning
Proceed or terminate notice	Before the deadline	Written notice to parties and escrow
Closing and deed signing	30 to 90 days after signing	Balance wired, notary executes and registers deed

If you are buying without visiting, the option can be signed remotely, and the deed can be signed under a power of attorney. Our remote buying guide explains how that works safely. Negotiation tactics for the offer stage are covered in how to negotiate property price in Nosara.

Questions to Ask Your Attorney Before You Sign

Bring this list to your first call:

Is this document an option, a reciprocal promise, or something else, and what can each side force the other to do?
When exactly does due diligence start and end, and how do I terminate?
Is the deposit refundable at my discretion or only for listed reasons?
Are water, access, zoning, maritime zone, inspection, and survey named as contingencies?
What happens to my deposit, and what can I claim, if the seller refuses to close?
Who is the registered owner, and does the signer have authority?
Does the Spanish version match the English version?
Should we record the option at the Registro Nacional for this property?
Can I assign the contract to my own corporation?

A good Nosara attorney will answer these in plain language and redline the draft accordingly. If they cannot, find another attorney before you wire a dollar.

The Bottom Line

The Costa Rica option to purchase agreement is short, often bilingual, and easy to underestimate. It is also the document that decides whether a failed water letter costs you nothing or costs you 10% of the price. Insist on third-party escrow, a due diligence clock that starts at funding, named Nosara contingencies, a real remedy if the seller defaults, and an attorney who works only for you.

When you are ready to put this into practice, browse current Nosara listings, compare neighborhoods like Playa Guiones, Playa Pelada, and Garza, and use our buyer's guide to map out the rest of your purchase.
